BL-Viz4D: A Digital Twin viewer for Maintenance
BL-VIZ4D is a research project led by Berger-Levrault, dedicated to the visualization, synchronization, and interaction with digital twins applied to maintenance. Stemming from thesis work conducted in partnership with the LIRIS laboratory (Laboratory of Image Informatics and Information Systems), BL-VIZ4D explores the scientific and technological foundations of a multi-scale 3D viewer capable of aggregating heterogeneous geospatial data—attribute, 2D, and 3D—and linking it to CMMS business processes. The viewer allows for
A Federated Learning Framework for IoT
There are thousands of institutions like hospitals collecting private and sensitive data, which mean they can not be transferred to be used. Though federated learning needs data to be trained. As we can not send them to a database like this (unprotected, non-confidential), a solution has been thought: each institution will locally train a model
BL.Predict, the clairvoyant of maintenance for Le Havre city
Imagine you won the lottery (yes, we all dream about it) and bought Versailles castle. You can not remember if you closed the bathroom tap on the other wing of the castle. Do not worry, you do not have to walk ten minutes long, you just have to check your phone app which will let
BL.Exchange, a solution to make softwares relationship friendly
Nowadays, the IT market is made of thousands apps with even more software options. Organizations are using different kind of apps with distinct sets up which evolves really fast for different purposes.
